To all whom it may concern Be it known that we, FELrX B. HORN and ADAM neuen, citizens of the United States. residing at Cedar Falls, in the county of Blackhawk and State of Iowa, have iiito show the spacing s ider in the hub; Fig.`

t is a view similar to "t ig. 2 showing a moditied form of spacing spider; and Fig. 5 is a side elevation of the *hub ortion of the wheel having the spacing spider of VF d, the front section being shown remove to show the spider more clearly.

'Fhe wheel of our invention consists of two complementary halves or sections findicated, as a whole, by A and B. These sections are formed out of sheet metal and each comprises a hub portion 1, a plurality of spoke members 2, a flat annular portion 3 in which the outer ends of the spoke members terminate, and .a tread portion 4. rlhe two halves of the wheel meet in a central plane C which is perpendicular to the axis of the wheel. 'l he walls ofthe hub ortions 1 are substantially parallel and orm an Vannular hub chamber H. rllhe spoke members 2 are concave in form and have straight p edges which come tosglthei" in the common meetin plane C. 'V en the parts are assemble the spoke members 2 form spokes which are el ptic in cross-section. The sides of the spoke members 2 converge gradually toward the outer edges to a point 5 `from which they converge suddenly at 6 to the meeting point 7 which lies in the plane C. From thepoints 8 at the outer end of the dat annular portion 3, the metal of the sections diverges outwardly at 9 and' then turns inward-ly at 10 to form the flat tread rim. When we say that the two halves or sections of the wheel meet in the common plane C, it is to be understood that we are together referrin y to the illustrations in the drawing where t e parts are shown fitting together perfectly. ln the actual construction of the wheel it is rare that such a perfect fit. is obtained and we wish to have it understood that the two halves of the wheel need only lit together as closely as thel working of the sheet metal permits to lform a wheel embodying our invention. Suitable i'astem ing devices such as bolts 1l ass through the .dat annularl portions 3. t will be observed Athat these portions are of considerable area and that in the assembled wheel they: term a connection of double thickness between the spokes and the tread rim of the wheel. l

ln the hub chamber H is located a spa-cin spider for holding the walls of the hu chamber apart. ln Figs. 2 and .the spider indicated, as a whole, by S comprises an inner rin 12 and an outer ring 13 connected y the portions 1 4, the ring being thus separated by elongated apertures 15. The substantially parallel walls of the hub portions 1 are provided with openings 16 around which extend annular recesses 17 formed by oisetting the metal of the hub portions. The ends of the inner ring 12 project into the recesses 17 to assist in holding the spider firmly in lace. The outer ring 13 o the spider projects into the `huh chamber 8 a considerable distance, so that a lar e bearing surface is presented to the wa ls of the hub chamber. Suitable fastening devices such as rivets 18 pass through the hub portions 1 and the apertures l5 of the spider, for rigidly clamping the hub portion against the spider rings. A bush ingl 19 extends through the hub openings and the spider. Sheet metal caps 20 engage the ends of the bushing 19 to prevent the same from working sidewise. The caps 20 are provided with outer flanges 21 which lie flat against the walls oi the hub chamber and through which the fastening rivets 18 pass.v The caps are provided with openings 22 in axial alinement with the opening of the bushinglll. y

In the modification shown in Figs. 4; and 5 the spider indicated, as a whole, by S comprises an inner ring 12 and an outer ring 15" connected together by the portions 14C. The two rings are thus separated by the apertures 15.J rlhe spider S is cast integral with 'the solid hub 23 for receiving the shaft of the wheel. The hub 23 is at its ends provided with an annular shoulder 24 formed on the ridges or corrugations 25.

The caps 20 abut around their openings against the shoulders 2li so as tolie flush with the outerends of the hub 23, thereby giving the wheel a neat and nished appearance.

If desired a reinforcing band consisting of a welded rod or wire 26 may be inserted in the tread chamber 27 formed by the portions 9 and 10 of the wheels sections.

Having thus described our invention, whatwe claim as new and desire to secure by Letters Patent of the United States is:

l. A sheet metal wheel consisting of two complementary halves or sections which comprise each a hub portion, spoke members with spaces between and a tread portion, the walls of the hub portions forming an annular hub chamber, fastening devices passing-through the two wheel sections near the outer periphery thereof, a spider arranged in the hub chamber to hold the hub portions spaced apart, said spider consisting of an inner rin and a complete outer ring connected toget er to present two annular` bearing surfaces tothe walls of the chamber, there being apertures provided between the two rings, a bushing extending through the hub openings within the spider, and fasv toning devices passing through the hub portions and the apertures in the spider for rigidly clamping the 4hub portions against the spider.

2. A sheet metal wheel consisting of two complementary halves or sections which comprise each a hub portion, spoke members and a tread portion, the walls of the hub portions forming an annular chamber, fastening devices passing through the two wheel sections near the outer periphery thereof, a spider arranged in the hub chamber to hold the hub portions spaced apart, said spider consisting of an inner ring and an l outer ring connected together to present two annular bearing surfaces to ther walls of the hub charnber, there being apertures provided between the two -rings, a bushing extending through said spider, retaining caps on the outside of the hub ortions which engage the ends of the bushing and clamp it in place, said caps being provided with openings in axial alinement withlsaid bushing, and fastening devices passin through said caps, said hub portions an the apertures in the spider for rigidly clamping the hub portions against the spider and securing the caps in place against theends of the, bushing.

3. In a sheet metal wheelconsisting of two complementary halves or sections and comprising each a hub portion, spoke members and a tread portion, the walls of the hub portions being substantially parallel and forming an annular hub chamber, fastening devices passing through the sect-ions near the outer periphery thereof, an apertured spacing member arranged between the parallel walls of the hub chamber and presenting considerable bearing surface to said walls, a bushingextending through the hub openings, retaining caps for said bushing,I

and fastening devices passing through said hub portions and the apertures in said spacing member to clamp the hub portions rigidly against the spacing member and to clamp said -caps against said bushing.

4. In a sheet metal wheel consisting of two complementary halves or sections and comprising each a hub portion, spoke members and a tread portion, the walls of the'hub portions being. substantially parallel and forming an annular hub chamber, fastening devices passing throu h the sectionsnear the outer periphery t ereof, an apertured spacing member 'arranged between theA parallel walls of the hubI chamber and presenting two annular bearing surfaces to said walls, a bushing extending through the hub openings, retaining caps on the outside of the hub portions for engaging the ends of the bushing, said caps being provided with openings in axial alinement with said bushing, and fastening devices passing through said caps, said hub portions, and the apertures lin the spacing member for rigidly clamping the hub portions against the spacing member and clamping the caps in place against the ends of the bushing.

5. A sheet metal wheel consisting of two complementary halves or sections which comprise each a hub portion, spoke mem-v the two rings, the inner ring extending at its ends into said recesses, a bushing extending through the hub openin s, and fastening de-- vices passing through t e hub portions and the apertures in the spider for rigidlyv clamping Athe hub portions against the spider.
